Caveats

method=convexhull

CIAO 4.12 has a new FOV algorithm which is available using method=convexhull which provides for a tighter fitting FOV. However, for observations where there are large changes in the boresite offsets (DY and DZ columns in the aspect solution file) the FOV may be too tight; the FOV may then inscribe the observed data.

The method=convexhull should only be used when the CONTENT of the aspect solution file is ASPOBISOL.
